The present invention 'comprises in its broadest aspect means for feeding sheets, fro t and rear blank cutting dies mounted at fixed stations in the path of sheets,` stops or-gauges in a) fixed Station for positioning sheets for the operation of the front blank cutting dies and other front stops or gauges adjustably mounted in the path of sheets for positioning sheets `for the action 'of the rear blank cutting dies. The adjustment of the stops or gauges with relation to the rear cutting dies determines the length. or width of the completed blanks.

The front and real` dies may be shaped and arranged to cut blanks longitudinally from theintermittently fed sheets, With flaps at front and rear of the blanks,-or these diesmay be shaped, and arranged to form the blanks transversely of the fed sheets with the flaps extending laterally of the sheet path. f e.. l

In the preferred embodiment of the pres#l ent invention, paper stock is supplied from a continuous roll through the feeding mecha: nism which passes the web of paper to an intermittentlyV operating knife, the feed of web being so timed with relation to the op eration of the knife as to determine the length of paper sheets that arevto be formed into blanks. The driving mechanism for the web feedincludes change gear mechanism for regulating the'speed of the feed with reference tothe operation of the sever\ ing knife, sol as to enable the operator to ent5k sizes of blanks.l In the operation of the improved blank cutting machine equipped with the 'described web feeding mechanism, the operation of lthe web severing knife is properly timed withrelation .to the blank cutting dies to properly supply a succession of sheets to said dies. lThe web severing` knife after each cutting action engages and arrests the leading edge of the continuous web, While, the rweb feed continues to operate and thereby forms a buckle of surplus 'material in the rear of the knife until vthe knife is raised and permits the passage of the 'desired length of web for forming a sheet supply sheets of different lengths for differ.

length. Each sheet length is arrested-With its leading edge in position for the action of the front blank cutting dies after which the formed leading edge passes to the adjustable stops or gauges, which position-the sheets for the action of the rear blank cutting dies. i

The completely cut blanks are passed out of the machine 'or delivered directly to a ina'- chine for making envelopes, envelope bags, "I

bags or boxes. X

The front edge cutting dies and back edge cutting dies are preferably combined at the same fixed station in the path of sheets so `that at each operation of the` cutting ies the rear edge is formed upon one blank simultaneously with the cutting of the `front 05 I edge upon the succeeding sheet. The dies are of sectional formation adjustable 'transversely of the sheet path to blank out different widths of sheets forvforming various sizes of blanks. 4' Y f The'invention includes other minor features of novelty in addition tothe above f pointed out important principles, all of' A which will first be described with reference to the accompanying drawingsand after- Ward more particularly pointed' out in the annexed claims. f In said drawings:

In the plan of the embodiment of the improved ,machine shown in the accompanying drawings, a suitable elongated framework is rovided to support the web and sheet or glank feeding mechanisms andthe cooperating knife, dies and registering Stops 0r gauges, with a shaft extending longitudinally of the machine frame at -oneside geared to the webl feeding mechamsm -and carrying cams for operating'thentermittently acting mechanisms, and asprocket chain or chains extending longitudinally of for driving the conveyers. This plan of machine is, Aof course, not essential t0 the present invention, but has been found an effective and convenient arrangementfof parts.' Y

The mainvmachine frame comprises two upright longitudinal side frames indicated at 1 and 2.- These side frames are provided at one end with a rigid bracket arm 3 braced by the adjustable support 4.` A roll supporting axle 5 'is freely journalled at its ends in the bracket arms 3and carries upon assauts its threaded` portion the adjustable conesy6, which engage the ends of the ordinary hollow mandrel of an endless roll of paper 10. By this mounting the roll of paper is rigidly held upon the-axle 5 so as to rotate with it. @ne end of the axle 5 projects beyond the bearing bracket 3 and carries a brake pulley 7 encompassed by a brake band 8 controlled by any suitable device, such as shown for regulating the unwinding of the web from the roll. j

Endless web 10 passes upwardly over feedrollers 15 and. 16 and around the Afeeding drum 17 above the feed roller 18. rl`hese rollers 15, 16, 18 `and drum 17 are all journalled in upward.,extensions of the side frames 1 and 2 and are geared together by a train of gears 20, 21, 22l and 23 to cause them to operate in unison.

An adjustable bar 25 engages the web 10 between the rollers 15 and 16. 1 This bar 25 is `suitably mounted upon the lowerends of adjusting screws 26, which are threaded in crossbar 27 0f the machine frame and are ,provided at their upper ends with sprocket wheels 28 around which pass an endless sprocket chain 29 to' cause screws 26 to rotate in unison.l @ne of the screws 26 is also provided with a crank handle 30 by which bar 25 can be adjusted to press downwardly more or less 'upon the web 10 between the rollers 1 5 and 16, to remoye the curl or natural set ofthe web as it feeds from the roll. K

Qne'feature of the present invention is the provision of adjustable change gear driving mechanism for the web feeding rollers'just described, to enable the opera tor to feed more or less of the length of web in a given time to supply sheets ofthe desired length. This adjustable change gear driving mechanism comprises a spur gear 30 keyed to the projecting axle of is `driven .by a spur gear feeding drum 17 in` position to mesh with and be driven by a broad, faced pinion 3l, which is carried upon a stud 32 adjustably mounted in the slot 33 of supporting arm 34 pivoted upon the axle of drum 17. A slotted bracket 35' projects from the machine frame alongside of thel pinion supporting arm 34. The slot in the bracket 35 is concentric with the axle of feed drum 17 and receives a clamping bolt 36 carried by arm 34 and provided with a clampingnut for 'securing adjusted position. l v l k his broad pinion 31 also meshes with and A 40" mounted upon the inner end of a stub shaft 41 journalled in-brackets 42 and carrying atits outerend a bevelled gear 43, meshing with a similar bevelled gear 44 on' the upper end of a short shaft 45 journalled in a bracket secured to side frame 1. vThe shaft 45 carries'at its lower end a bevelled gear 46 meshing with the arm 34 in the desiredJ journalled upon a long shaft 50, which extends from end to end of the machine frame atl one side and is suitably supported by `bearingrbrackets 51. A sliding clutch member 55 is/splined upon shaft 50 adjacent to the bevelled gear 47 and engaged by an operating lever t56 pivoted upon the machine 34. It is proposed to provide a machine ofthe embodimentV illustrated with a number frame 1, by which bevelled gear 47 may be clutched or released upon shaft 50. The clutch operating lever 56 /is connected at its upper end with a rod 60 which passes 'through suitable supporting bracket arms 61 and extends to the opposite end of the machine where it is provided with an actuating handle 62. An adjustable collar 65 is clamped. upon therod 60 ii position to engage one of the brackets 61 for limiting the clutch applying movement of rod ,60. The handle 62 is also adjustably mounted upon rod 60 in osition to engage bracket arm 61 for linnting theI clutchvrelea'sing movement of rod 60.I

' The pinion 31 above i'eferred to is adjustably mounted upon its supportingarm of interchangeable pinions 31 graduated in size, so that by'applying theproper pinion proportioned with relation to the rest-of the gearing, any desired ratioof feed of web or the vproduction of the selected sheet length can be obtained; The desirability of accurately 'cutting sheet lengths to suit the sizeof blanks to be made is not only becausel of economy of stock, but as will hereinafter appear for the most' efficient cooperation with the composite dieof the blanking out mechanism;

is a transverse shaft `freelyjournalled in the upward extensions of the machine side frames above feed roller 15. This shaft 70 is geared through pinions 71, 72 with one end of the axle of feed shaft`15. The purpose of shaft 70 is to provide means for trimming the edge of the paper web as it is fed from the roller. The trimming cutter that may be applied to this shaft 70 is not shown, since the structure and mounting of such trimming cutters are well understood in the art and form `no part of the present invention. i

The end of web 10 passes from rollers 17, 18 on to the upper horizont-al runs of the series ofa endless` feed belts operating around the belt rollers76 and 77. Thebelt roller 76 is journalled Iin fixed bearings 7 8,

- while the belt roller 77 is journalled in the i The axle of belt roller 77 projects beyond bearing at one side of the machine and carries a sprocket wheel 81 by which the series of belts 75 are constantly driven. A

belt tightening noller 85 formed with a'seriesy of deep annular grooves engages the lower runs of belts 75. This belt tighteningside frames and are provided with adjusting.

nuts 88 to effect the raising and lowering of the roller 85 to tighten or loosen the belts 75.

The conveying belts 75 carry the web 10 forwardly over the lower stationary knife lplate or member 90. Spaced above the knife plate 90 is a curved guide plate 95 forming with the knife plate 90 a gradually contractlin,.1jthroat for leading the web 10 to the cutofi' knife and confining it adjacent to the path of thej-knifegduring the operation of cuttingwoff a sheet. A series of guide rods or. fingers 96V project rearwardly fromthe guide plate to'assis't in guiding the web and confining it in the rear of the knife. A series of rotary brush'es100 are. mounted Y upon the shaft 101 above the plane of' feed of the web4 in posit-ion to engage the web and keep it brushed .up to the plane of action of the cut-off knife and restrict the bulge or buckle off surplus web material to a position in rear of the brushes, so as not to interfere with the accurate action of the cut-off by the sprocket chain hereinafter referred to. i

.110 is a vertically reciprocating cut-off knife mounted upon the crossh-ead 111 mounted in vthe vertical guideways 112, formed in the upwardly presented brackets 113 mounted upon the machine side frames.

The knife crosshead 111 has pivoted'to' its il opposite lend the` downwardly 'extending links 114 pivotally connected at their lower ends to the rock arms 115 adjustablymounted upon a rock shaft 116,- which extends from side to side of the machine and is suitably journalled in the machine side frames. This rock shaftv 116 carries at one end a rock arm 117 which-I operates in a grooved cam 118 `mounted upon the shaft 50 above referred to. 110 to operate once for each revolution of the shaft 50. J

The knife 110 is normally at rest in elevated position to permit the passage ofthe The cam 118 causes the knife leading edge of web 10 over vbed plate 90 i and under knife 110, the webv passing beyond the vertical plane of action of the knife on to the upper yrunso/f a second series of endlessconveyer belts 125 operating u 'on the belt rollers/ 126 and 127, which are i mounted respectively in the vertically adjustable bearing brackets 130 adjustably supported from the machine upon the upright Iscrews 131 by means of nuts132..

Upper endless conveyer belts 135 are suring accuracy in the feeding operation..

mounted upon the belt rollers 136, 137 in cooperative relation with the lower conveyer belts 125 and serve to engage sheets and upress them agamst the lower belts tor 1n- "lhe \belt rollers 136, 137 are adjustably mounted upon the upper ends of the screws 131 above referred to 'and are connedl thereon in the desire adjusted positions by means of nuts 138 threaded upon said screws above and below the bracket bearings in which the belt rollers are journalled. The belt rollers 136 and 137 are formed of cylindrical sections and their shafts 136u and 137a have is mounted upon them between the roller sec one sigle of the machine and have mounted there which engage the sprocket chains hereinaft-er referred to for imparting continuous motion to the belt rollers, belts and brushes.

belts rollers 147 and 156 are provided with sprocket wheels 149 and 150 for the engagement of, the driving sprocket chainhereinafter referred to. v

In addition to the two sets of endless conveyers 125, 145, there is a long wide conveyer `belt 160 passing centrally through the machine over the belt rollers 126, 127, 146 and 147 and back under a guide pulley 165 to the rst mentioned belt roller 126. The guide the endless conveyer belts 125 and 145 and the upper runs of the the sprocket wheels 141, 142 and 143,

mounted above.the conveyer belts 145y 'upon belt rollers` 156, 157 carrying rotary.

' nascose upper endless belts 135 and 4155 are engaged between their supporting belt rollers by 'some suitable from of slack take-up or belt tightening device. ln the accompanying drawings tour series of one ytorno of such belt tightener is shown applied tothese endless belts. A description of one of these devices will be sufcient for all, since the structure is identical in the several devices.

Each of these beltjtightening devices referredqto comprises a lever 175 having journalled in its opposite ends the rollers 176, which respectively engage the upper and lower faces of one of the endless belts. 'llhese levers 175 are pivotally mounted upon a transverse rod 177 carried at its ends upon brackets 178 adjustably mounted upon upright posts 179 projecting from the machine sidel frames. A. weighted lever arm 180 is pivoted upon.' the rod. 177 alongside of the belt tightening lever 175 and is formed with a rearwardly projecting .heel 181, which engages a pin Y182 projecting lat-erallyirom the lever 175; thereby giving said belt tighteninglever a normal tendency to take up the ,slack yand tighten the endless belt upon which it is applied, the belt engaging rollers 176 pressing upwardly upon the belt at one side of pivot 177 and downwardly upon the belt upon the opposite side ot pivot 177 to accomplish this purpose. It will be/observed that'there is an individua-l and independent belt tightening device for each endless belt, and that further the several belt tightening devices for each set of endless tbelts are mounted upon a common supporting pivot rod 177.

lt will also be observed that in Figure 5 of the drawings, the machine is shown with six 'lower conveyer belts 125, and four upperbelts 135, and in Figure 4 with eight lower belts 145 and four upper belts 155. The number and arrangementof these belts can bel arranged to suit vthe particular size of sheets and character of stock operated upon.

185 is an idler belt roller vsupported beneath the upper runs of endless belts 125 and feedv belt 160. said roller 185 being adjustably supported at its ends in the same man-v ner in which the otherbelt supporting rollers are mounted.

Immediately below the plane offeed-of sheets adjacent to be`.t roller 127 is mounted a track/bar 190 adjustably supported at its ends upon the upright pins orstuds 191 projecting from the machine side frame.

lide blocks or carriages A195 are mounted upon the track bar 190 with freedom to reciprocate inwardly and outwardly transversely of the machine, each` of said memlll' en u

bers having removably mounted upon v present the horizontal portions of the gauges tween the belt rollers 127 and' 146 i's mounted.

196 beneath the plane of feed and the vertically and longitudinally presented side gauging flanges intersecting the plane of feed, so as to engage theedges of passing sheets and accurately guide them into the" proper longitudinal path to present them to the flap cutting dies hereinafter'explained.

' These side registering gauges 196 have their tate' the ent horizontal and vertical walls flared respectively downwardly and outwardly to faciliof sheets between the gauges.

At one si e of the machine an operating lever 200 is pivoted upon the supporting pin or stud 191 and carries at opposite sides of its pivot the upwardly presented blocks 201 through which project the threaded endsl of the rods 202, projecting from the pivoted blocks 203 mounted upon lugs of the reciprocating carriages 195. The threaded ends of these rods 202 are engaged by the screw nuts 204 presented' at opposite faces pivot with'a pin or lug of blocks 201 to afford adjustable connections between the rocking leverJ 200 and the reciprocating carriages which support the gau es 196.

an open oblongr'bed frame 225, which rests upon the machine side frames and is securely bolted thereto. This open bed frame 225 yis formed with,- inwardly presented shoulders or ledges 226 upon which rest the two` lower members 230 of the composite die. Each of these lower die members 230 cornprises an open rectangular base having upright walls 231 projecting from it. Secured to these walls 231 by means of set screws 232 are the knife blades 235 which are en;

gaged above the lines of their attachment.

to Walls-231 by a series of adjusting screws 233, which pass through the .walls 231 into engagement with the blades 235 for the purpose ofaccurately presenting said blades in cutting relation to the upper composite die sections presently to be described. At the inner end' of eachI lower die member 230 is mounted a cutting plate 236 formed with cutting edges 236g, '236b presented at angles.

to the cutting blades 235 referred to. 'At the outer edge of each lower die member 230 is mounted an angular bracket 240 secured by means of set screws 241, upon T e level` 200V is connected through a, link @which bracket is pivotally mounted at 242 205 with a lever 206 pivoted at 207 upon a bracket arm 208 secured to the machine side frame. Lever 206 vcarries at its lower end an antifriction roller (not shown) which operates upon the periphery of a cam 210 secured to the shaft 50 above referred to. A spring 211 connects lever` 206 above its 212u on the machine side frame The escribe( mechanism causes the side registering gauges 196 to intermittently move toward and away from each other for accurately positioning a .passing sheet inthe central zone of the machine,

y preparatory to its presentation to the vflap cuttin dies which will now be described.

. lThe dies for blanking out the front and rearedges of sheets may be separate devices brought into action at proper times, but these dies are preferably formed as in the l embodiment illustrated in the accompanying drawings, in which they are arranged to simultaneously cut out the leading edge of one sheet and the rear edge Of-a preceding sheet, separate gauges being provided for independently positioning the two sheets with respect to the front and rear die portions. In addition to the preferred composite form of blanking out dies, it is also desirable to form these composite dies of independently 'adjustable parts or members,

' which are separated in the central longitudinal Vzone of the machine so that the parts or sections can `be vadjusted inwardly and outwardly toward and away from each other to effect the required -lateral spacing of the .y dies to produce envelope or other blanks of different sizes.

Arranged transversely of the machine bewith a stop pin `249 projecting laterally from the lever 243.l This trip member 246 is' presented normally above a block 250 bolted to the outer end 'of one ofthe walls 231, so.

that the downward movement of lever 243 will cause membgr 246 to'engage block 250 and rock the shaft 244 against the restraint of spring 247 with the result that the chip ejecting plate 245 will bel shifted from its normal position-to a more abrupt inclination as shown in Figure 7 of the drawings, to cause a' chipT of paper to slide from the plate down into the opening in the die supporting bed frame. Thelever 243' is formed llO with an opening 243a extending through it l and a'A guide bolt 255 projects upwardly I from thetbracket 240 through said opening 243, an expansion spring. 256 being confined upon the bolt 255 between bracket 240 and lever 243 for yieldingly supporting the lever 243 in its raised position. Nuts 2,57 are threaded upon the upper end of bolt 255 for limiting the upward vmovement of lever 243 and for accurately adjusting lthei normal position of said lever to produce the desired cooperation of the .chip ejecting plate and the bl liking out dies.I

These lower composite die members 230 lll 'A journalled in the machine: `Iframes.

are `secured inthe desired position in the openbed frame 225 by means of bolts 260, which pass through any of the series of openings 225a in the upright walls of frame 225 and impinge against the sides of the die members 230. By this means the two lower'die members 230 can be readily adjusted inwardly and outwardly upon' their ciprocate freely 1n the vertical sockets 277 of the guide brackets 278 securely bolted to the machine frame at opposite ends offthe .bed frame 225 above referred to.- Guide pins 290 project upwardly from the brackets 278 and pass freely through vertical openings 275 `in the crosshead '275, cushion springs 291 being mounted upon the pins 290 between brackets 278 and the crosshead 275. The opposite ends of crosshead 27 5l are provided with bearing pins 295, upon which are pivoted the upper ends of pitman 296 connected at their lower ends to crank pins 297 upon crank disks `2.98, which are carried by a transverse shaft 300 fir'lelelly 1s shaft 300 is provided inside 'ofvone of the side frames with a spur gear 301 which meshes with a similar gear. 302 upon a transverse shaft 303 journalled in brackets lformed upon the machine side frames. This `shaft '303 carries at its outer end a worm gear 304 which meshes with and is driven by al similar worm gear 305 keyed to the machine By thedescribed mechanism the crosshead 275 is caused to rei ciprocate vertically upon its guides.

This crosshead 275 isformed with two vertical slots- 310 arranged upon opposite sides of -the central vertical longitudinal,

plane of the machine to receive the screw bolts 311, which are threaded into the upper composite die members 315 and support them in the desired adjusted position upon the crosshead. A suitable gauging sca-1e. 314 is mounted upon one face of the crosshead 275 and indicator fingers 313|'are mounted upon the 'adjustable upper die members 315`to indicate .at a glance the desired posit-ion for the die members for the particular size of envelope or box blank to be made.

, The crossheadl 275 is formed with ati Lied under surface indicated at 275" `plates 320 remain in elevated gauging posibers This result can be to engage s l the upper'surfaces of thedie members 315. belts 125 to the blanking out assente For cooperating with the-composite lower die members abovev described, these upper die members are constructed as illustrated in detail in Figure 11 o'f the drawings, in which the block or carrying member 315 has sey cured to its under lface a cutting plate 316 formed with main cutting edges-316a and 3161 designed to cooperate with the cutting blades 235 of a lower die member and the angular cutting edges 316c and .316% which cooperate with the cutting edges 236a and 236 of the lower die member. Each upper die member 315 carries a, downwardly pre sented tappet member 317 which is presented 1n position to engage one of the levers 243 80 of the chip ejectorofl the ylower member, causing the lowering of lever 243 when the upper die member moves downwardly during a blanking out operation.

320 are vertically presented gauge plates @5 or stops mounted at their lowerends upon blocks 321' which are journalled upon a transverse shaftl322 carried in the ffree ends of rock arms 323 adjustably secured to a rock shaft 324. .f The rock shaft 324 is jourlnalled at its ends in the bracket arms 324a projecting from the machine side frames. The sha-ft 322. carries near its opposite ends antifriction rollers 3257 which operate inf peripheral engagement with the cams 326 nounted upon the shaft 300 above referred t is desired to have the gauge or stop tion until the descent of the upper die memaccomplished by the accurate timing of the operating cams 326, but If have found a simple and efective means for the purpose to be the provision 7of a suitable braking device for'the rock W5 shaft 324, so that the gauge members will be raised by the cams and remain in elevated position vuntil they are pushed back by the action of the-blanking out'dies. In v the form of this mechanism ,shown in the no drawings, it will be observed with particular j reference toFigures 2 and 9 that two strips of wood 330 are notched upon their inner faces to `lit over`the shafts 300 and 324, clamping bolts 331 passing through the 115 strips 330 uponv opposite 'sides of theshaft 324 to clamp them upon Said shaft with more pr less pressure to produce the desired frictional engagement with the shafts.- -The stop gauges 320 are provided with guidJTZO pins 320EL which project froml them and guide upon the inner face of 011e of the transverse frame bars to guide and brace said stops.

The stops 320\ are presented up through the hollow lower die members in the 'path-125 i of 'sheets to engage the. leading edge of\a sheet and arrest it in position for thevblanking out of said leadingedge. p

Sheets are 1 directed from the conveyer dies by. upper j bearings of the upper belt roller 137. 338,f

338 are the centrally spaced lower guide plate sections, mounted upon screws 339 projecting upwardly from'the composite lower die members 330 and adjustable transversely ,of the machine with said die members.

340 are stripper members, each having angular forwardly presented faces shaped to approximately conform to the cutting edges 235, 236,1 of a lower die member land the cooperating cutting edges 316" and 316dl of an upper die member. The .upper die members move vertically past the stripper members, which latter confine the blanked out sheets in the plane of feed and strip them from the upper die members after a cut. 'llhese stripper members 340- (of, which there are two spaced laterally on the ina--l zhine) are formed of channeled plates fitting upon the upper surface of transverse bar 336, Said bar being formed with a number of vertically presented threaded perforations 3361 to receive clamping screws or bolts 341 Iwhich .pass through elongated slots 342 in the channeled portions of the stripper mem' bers and engage 1n certain of said perforations for Securely fastening the stripper members to bars 336. By this means the stripper members 340 can be. convenient-ly adjusted transversely of the machine to suit the adjusted position of the composite die members. f f

- After each operation f the blanking out dies the sheets are carried forward by the constantly running belt 160, one sheet being arrested by the gauges 320 as already explaine-d, and the' blanked out leading edge of the preceding sheet being arrested by the gauges 345, shaped as shown specifically in Figure 17 of the dra-wings to engage the leading angular face of the partially formed blank. These gauges 345 are mounted upon the lower ends of arms 346 formed with laterally extended steadying sleeves 347, which are adjust-ably'mounted upon the 'rock shaft 348 yand are secured thereto by thumb screws' 349. The gauges 345 are adjusted laterally of the machine upon shaft 348 to accurately enygage the leading blanked out edge of a sheet.

The rock shaft `348 is freely.Y journalled in the upper ends of brackets or auxiliary side frames 350,' which are designedto slide forwardly and backwardly upon the rack bars 351 suitably secured to .extensions of the machine Siderames. These bracket frames 350 have freely journalledein them, just above .the rack bars 351, a transverse shaft I 352 carrying near its opposite end pinions 353, which mesh with the rack bars 351, said shaft 352 also having at one end a handdelivery end of the machine.

shifted forwardly and backwardly to posi-- tion the gauges at the proper distance from the blanking out dies `to shape the rear edge of a sheet for the desired length of envelope or box blank. lThe brackets 350 also,have

yrearwardly presented arms 350s carrying a transverse tie rod 356 ron which are adjust ably mounted the fixed side gauges 357, which are designed to engage a moving sheet to accurately present it t-o the stop gauges 345 above referred to. rlhese side gauges 357 are presented upon opposite sides of the path of sheets, their position being accurate ly located to suit the particular size of sheet being operated upon.

The gauge supporting rock shaft 348 carries yat one end, a rock arm 360 provided with an antifriction roller 361 and held by spring 362 in constant engagement with a vertically reciprocating cam bar 365. This cam bar 365'is mounted on the upper end of a vertical bar 366 formed with elongated slots 367, 368, through which pass the guide bolts 369 seated in' suitable brackets upon the machine frame for accurately supporting and guiding the bar 366 in its vertical reciprocation. This bar 366 also carries an antifriction roller 37 0r which operates in peripheral contact with aicam 375 secured to the shaft 50 above referred to. l This cam 375 is preferably of sectional formation to facilitate the timing ofthe operation of the cam bar 365. By the described arrangement of operating mechanism for the stop gauges 345, it will be observed that the'ugauges can be readily adjusted Ifor various sized Sheets without thenecessity of changing the operating mechanism, the roller 361 of rock arm 360 moving freely upon cam bar 365 when the gauges are adjusted and always re-A maining in operative relation to the cam bar.

The gauges 345 arrest sheets in position to present their4 rear edges to t-he action of the rearedge blanking out parts of the composite dies. of the dies, the gauges 345 are rocked out of the, path of the sheets to permit the con# veyer belts to pass the 'completed blanks to the final set of gauging sheet stops at the sheet stops 380, shown in `detail'in Figure 17 of' the drawings, are the same shape as Immediately after the action i These filial the stops 345 just referred to, so as to a-ccurately engage the leading edgey of the blank. Stop plates 380 are adjustabljT mounted upon the rod 381 supported between the upper ends of arms 382 carried by a rock shaft 383 suitably journalle'd in,l

extension brackets -of the machine side,` frames and carrylng at one end a rock arm 384 operating in engagement with a cani A385 upon shaft4 50. A spring 386 holds the rock arm 384 in operative relation to 385.

Just prior to the arrival of the blanks at Calm the iinal stops 380, they are preferably given other, for positioning al blank upon the conveyer, by means of a pivoted lever 395 ad- Vjustably connected upon opposite sides of its pivot through rods 396 with the respective guiding blocks 391 in the same-manner as above described with reference to the side registering plates 196. The leverw 395k is connected through link 397 with a veitical lever 398 pivoted to amachine bracket 399 and carrying at lits lower end an antifriction roller 400 operating upon a cam 401 mounted on shaft 50. A spring 402 holds the lever 398 against the cam 401.

Completed blanks may be delivered from the machine to 'a pile, or they may be taken directly from the improved blanking out machine by an envelope or box machine for forming the blanks into completed articles.

The machine for operating upon the complete blanks formsno part of the -present invention, but parts of an envelope ma- ,chine -of the type covered by my Patent No. 1,000,057 of August 8th, 1911, are illustrated in Figures 1 and 2 of the drawings.

In these illustrations 405 is a gripper cylinder designed to take successive blanks from the gauging final stops 380 and pass them to the envelope machine.

In the embodiment of theinvention illustrated in the accompanying drawings, the

shaft is intended to vbe driven from the envelope machine as well as the chain drive for thef conveyers which Will now be referred to more in detail. A train of gears- 410, 411 and 412, shown as driven from the gripper cylinder 405 of the envelope mach1ne,'directly drive the large belt roller 147 at the delivery end ofthe machine. As

0 above explained the axle of this belt roller 147 carries a; sprocket wheel 149, which drives 'a sprocket chain 415 operating around the sprocket Wheel 141 upon lower `-belt roller 127C, said chain passing beneath and in engagement with the sprocket wheel 150 of theupper belt'roller 156. .Guide pulley 150a supports chain 415 adjacent to sprocket Jwheel 150. A secondsprocket chain 420 passes around the Second sprocket wheel 142 of lower'belt roller 127 tothe sprocket wheel 81 on belt roller 77, the upper run of said chain passing beneath and engaging the sprocket wheels 103 and 143 above referred to. Guide pulleys '103'l and 143a engage the chain'420 adjacent to sprocket wheels 103 tary brushes are driven from a 4part of the envelope machine. i y

Figuresl and 17 of the drawings illustrate the successive steps .of forming blanks from -a continuously fed paper web. In these illustrations, it will be observed that the front and rear iaps of the envelope blanks are cut longitudinally of the machine or of Lthe path of the sheet material. ,In Figures 18 to 21 several slight modifications of the method of operating the new machine are illustrated. In these modifications the blanks are formed transversely of a 'longitudinal traveling web, that is the sheets arel blanked out with their fiaps extending transversely of the sheet Apath and the sheets and blanks progress sidewise through the machine.

' lIn the operation of the improved blank-v ing out machine, the\web of paper is fed continuously to the cutting olf knife 110 at the proper speed with relation to the timed operation of the knife, to insure the The front and rear edges of the completed blanks are coincident with the front and rear edges of the sheets carried forward by the conveyer from the cut off knife 110.

The successive sheets areJ arrested by the' gauges 320, n t by the gauges 345 and linally by thegiuges 380. At each-opera tion of the blan :ing out dies in their fixed `station in the sheet path, the leading edge of one sheet is cut out simultaneously with the'rear edge of the preceding sheet, 'it being clear with particular reference to Figure 17 of the drawings,rthat two sheets 'are gauged in successive i positions with rela.l

tion to the composite vdies prior to every operation of the dies.l

The sheet guiding and chip ejecting plates Y 245 rest`normal1y in positionv toxguide the side edges of the advancin sheet over the rear flap cutting blades ofower die members, the central portionfofthe sheet rest-- ing'upon belt 160. Immediately following the cutting action of the dies, the levers' 243 Aof lower die members are engaged by tappetj members 317 of the upper` die members to cause the rocking ejecting the chips.

It will be clear'that-blanks of different widths can beformedby using differentl widths of web from which different' lengthsl of ejecting plates 215vfor of sheets "can be cut, which `are blanked out with the proper sizes of front and rear fiaps by proper adjustment of the composite dies transversely of thek machine and the adjustment of the gauges 345 longitudinally l `the mounting of blanking out dies of the proper design and the arrangement cand adjustment of the gauges to suit the changed form and/manner of handling the blanks. In this modified form of the machine, an additional set of stops is shown to illustrate the mountingof suitable rein forcing patches and closure devices upon the blanks prior to the formation of the envelopes. For instance, in Figure 19 of the drawings, a blank is shown with a reinforced perforation at a; to receive one of the well known fastening devices shown at lln Figures 18, 19 and 2O the elements of a folding mechanism are illustrated to show the application of a different form of 'envelope machine to the continuous blanking out machine of the present invention. Figure 21 isa diagrammatic view of an envelope blank of the form shown in Figure 19 having the illustration at a of a different form ofireinforcing closure device. These forms of blanks, both with and without reinforcement patches and closuredevices, are

well known in the art and are not specifically claimed in the present application, but are shown dia rammatically in the drawings simply as i lustrations of possible extensions in the uses of the improved machine. `lit will be observed that in any of.

l the suggested forms of the machine, the

main operating devices, such as the cut-oft1 knife, the blanking out dies, the patch and closure applying devices and the attached envelope machine are all mounted at fixed stations in the web pathl of the machine and that such devices always remain in said stations irrespective of the sizes of blanks being produced. rlhe differences in sizes are provided for by the simple adjustments'explained which do not require alternationof the devices which operate upon the sheets for determining the character of the blanks.

One of the important advantages of the improved blanking out machine resides in the simplicity of construction and thecreadiness with -which the machine can be adjusted for producing dierent sizes of 'envelope blanks. The blanking out dies being mounted .at a fixedstation in the-sheet path with the first -set of stops always operatin in the same station, it will be clear that to change the, machine to produce a desired size ofblank, it is only necessary to yother devices for producing blanks of dif- 3 ing sheets.

correct rthe speediof the web feed by the means set forth to produce the proper length of sheets, then adjust the second set of stop gauges to accurately correspond with the length of sheets and transversely adjust the composite die members to form the required ,flaps upon the sheets. The side registering gauges and final stop gauges can then be transversely adjusted to suit the width of flaps upon the blanks to be formed. These adjusting operations are much more readily and accurately performed than the shifting and adjusting of the punches and dies and ferent sizes and, character as has been the practice heretofore. With the improvedJ machine the length of the blank or sheet is first determined and the blank completed by cutting away certain portions from the corners of the sheet. lIn the past the usual practice has been to determine the size of the blanks by the adjusted relationship between two sets Vof punches and dies which operate upon continuous webs or sheets in excessof thecde'sired blank sizes. l
